Abstract

In a dubbing apparatus capable of prohibiting next high-speed dubbing of a piece of data once completing high-speed dubbing for a predetermined period of time in a process of high-speed dubbing from a first recording medium to a second recording medium, such a piece of data cannot be dubbed at a high speed but can be dubbed at an ordinary speed during the predetermined period of time in response to a request for re-dubbing of the piece of data at the high speed. It is thus possible to achieve an object of the dubbing apparatus to protect a copyright for prohibiting an operation to copy data to a plurality of recording mediums at one time.When the user issues a command to again carry out high-speed dubbing of pieces of data, high-speed dubbing of pieces of data once subjected to high-speed dubbing during the predetermined period of time is deferred. Pieces of data not subjected to high-speed dubbing during the predetermined period of time are dubbed at a high speed, taking precedence of the pieces of data once subjected to high-speed dubbing during the predetermined period of time.
